Supply chain engineering and management

供应链是物流和制造活动的网络，从原材料采购到成品分销到市场。一个完整的供应链通常包括几个公司和几个生产/仓储设施。给定产品市场的供应链绩效严重依赖于两个相互依存的战略问题：1)网络结构，即参与企业的数量、位置、使命、技术和设施能力；2)使用的物料流计划和控制过程，即用于准备总体计划，计算需求，批量，安全缓冲等的方法，以及为网络中的各个生产/分配阶段安排操作。我的研究涉及：1)在全球范围内，开发方法和工具来评估潜在的结构性和程序性供应链战略；2)在更详细的层面上，通过数学模型的制定和求解，可以用于优化供应链网络结构或在特定情况下规划物料流。在这两种情况下，都努力制订模型，以便将其纳入具体工业部门的分布式规划系统。

Supply chains are networks of logistic and manufacturing activities starting with raw material sourcing and ending with the distribution of finished goods to markets. A complete supply chain usually involves several companies and several production/warehousing facilities. The performance of a supply chain for a given product-market critically depends on two interdependent strategic issues: 1) the network structure, i.e. the number, location, mission, technology and capacity of the facilities of the firms involved; 2) the material flow planning and control processes used, i.e. the methods used to prepare aggregate plans, to compute requirements, lot-sizes, safety-buffers, etc., and to schedule operations for the various production/distribution stages in the network. My research is dealing: 1) at a global level, with the development of methodologies and tools to evaluate potential structural and procedural supply chain strategies; 2) at a more detailed level, with the formulation and solution of mathematical models which can be used to optimize the supply chain network structure or to plan material flows in specific contexts. In both cases, an effort is made to formulate models which can be integrated in distributed planning systems for specific industrial sectors.
